MODELLING THE CAISSON PLACEMENT AT THE CHIOGGIA INLET, VENICE

Bas Hofland, Nico Vink

Abstract


In the summer of 2014 Strukton Immersion Projects has placed the foundation caissons of the Venice flood barrier in the Chioggia inlet to the Venice Lagoon. The caissons were loaded by currents and waves during placement. Before the placement, physical model tests were performed in a wave-current basin to optimize the placement procedure, and to determine the line force and pontoon motions. This paper describes the model setup, tests that were performed, the results and the implications for the placement procedure. Also the experiences during actual placement are discussed.
